Next, the knitting process of the product of the present invention will be specifically explained. 5(a) to 5(f) are explanatory diagrams showing the knitting process of the product of the present invention, and FIGS. 6(a) to 6(f) are explanatory diagrams showing the knitting method of the product of the present invention. As shown in (A), a constituent portion 3a of the string passage hole 3 to be formed at one longitudinal end of the cover body 1 is knitted. The lace hole component 3a is knitted using two colored threads A, for example, as shown in FIG.
1゜When using A2, - of colored threads A1
Use the front needle bed F, 1! (e) Rubber knits that are alternately hung on both latch needles of the needle bed B are knitted by a length corresponding to the length of the string passage hole constituting portion 3a, for example, from the left side to the right side.

In this process, the other colored yarn A2 follows the preceding colored yarn A1 and performs normal stockinette knitting, for example, only on the latch needles of the rear needle bed B.

When knitting is completed by a length corresponding to the length of the string threading hole component 3a, it is folded back at that position, but in this process, as shown in FIG. A2
Perform stockinette knitting only on each latch needle on the rear needle bed B.

In this way, after reciprocating the required course, when the width dimension d shown in Fig. 5 (a) reaches a width sufficient to pass the rubber cord 4 (number of stitches = 6 to 7), it will move forward as shown in Fig. 6 (c). The colored thread A1 to be threaded is stockinette knitted only on the latch needle of the front needle bed F, and the colored thread A2 to be followed is knitted in rubber knitted on the latch needles of the front needle bed F and rear needle bed B alternately. The knitting of the hole forming portion 3a is completed. As a result, a string hole constituting portion 3a with both ends open is knitted. When the knitting of the string hole constituting portion 3a is completed, a jacquard knitting is performed in which <r4S forms an arc, as shown in FIG. 5(b). In this jacquard knitting, for example, when the pattern is a checkered pattern, as shown in Figure 6 (d), different colored threads A and B are used, and the preceding colored thread A is not removed from the rear needle bed B. (For example, on the front needle bed F, hang on every 5 latch needles, while the trailing colored thread B
Similarly, do not remove the needle at the rear needle bed B (hang,
In addition, on the front needle bed F, the latch needles on which the colored thread A is hooked are removed from the latch needles on which the colored thread A is hooked, and knitting is performed from the left side to the right side, respectively.

After knitting a length corresponding to the length of the string hole component 3a, turn back from that position and knit in the same manner as above, repeating this for the required course, but several times each time the left end and right end are reached. The arcuate edges 1b, lb, and la are to be sewn later at both ends by gradually increasing the overall width dimension as shown in FIG. 5(b).

1a are formed respectively.

The number of stitches may be set appropriately so that the arcuate edges 1b and la can be formed into a desired curve.
, la are arranged so that their arc lengths and radii of curvature are mutually equal.

When the knitting of the arcuate edges 1b and 1a is completed, as shown in Fig. 5 (c), the knitting is the same jacquard pattern with the same checkered pattern.
Knitting is performed to form string passage hole constituent portions 3c and 3d, which constitute part of the string passage hole 3, at both ends.

In this knitting process, as shown in Fig. 6 (E), for example, the preceding colored yarn A is hung on the five latch needles of the front needle bed F at the beginning of knitting in the rightward process, and then as shown in Fig. 6 (D) above. Perform the same jacquard knitting as above, and when you reach the right end and finish knitting, hook it onto the five latch needles on the back needle bed B, and then knit on the front needle bed F at the beginning of the leftward process.
5 latch needles, and perform bag knitting on the right end for 5 latch needles. After that, perform jacquard knitting, reach the left end, and at the end of the knitting, wrap it around the 5 latch needles on the back needle bed B, and perform bag knitting on the 5 latch needles at the left end in the same way, forming string passing holes at the left and right ends respectively. Parts 3c and 3d are knitted. Note that the knitting mode of the following colored yarn B is also substantially the same.

In this way, the material of the cover main body 1 having the string passage hole forming portions 3c and 3d at both ends is knitted by knitting the middle part with a checkered jacquard knitting and the both ends with bag knitting. In order to form the string passing holes 5a and 5b several times at approximately the center in the longitudinal direction as shown in FIG. 5(d), as shown in FIG. 5(a) and FIG. 6(a) in the same manner as described above.
Perform rubber knitting, stockinette knitting, and rubber knitting as shown in , (b), and (c).

As a result, string holes 5a and 5b are formed which are located on a straight line, are interrupted at the middle part, and have openings at both ends.

In the embodiment, a case is shown in which there are two string passing holes 5a and 5b, but it goes without saying that a plurality of string passing holes may be formed in a straight line or in parallel.

After that, the same pus growth as shown in Figures 5 (C) and 6 (E) repeats again, but in the middle of this, Figure 5 (E)
The insertion hole Sr of the column 13a of the headrest 13 as shown in FIG.
, 81 are organized.

These insertion holes 8r, 8j! The formation of is shown in Figure 5 (E), 6th
As shown in the figure (f), there are two insertion holes 8r and 8j! Of these,
First, the region 8a on the left side of the left insertion hole 8r is knitted,
Next, the intermediate area 8b of both the insertion holes 8r and 81 is knitted, and finally the right (1'J area 8c) of the right insertion hole 82 is knitted.

That is, the knitting of the left region 8a of the left insertion hole 8r is a jacquard knitting for forming a checkered pattern, as shown in Fig. 6).
As shown in the figure, both the leading and trailing dyes A and B reach the left end and grow to the point where the insertion holes 8r and 81 are to be formed, turn back at this position, and repeat between the insertion hole 8r formation position and the Fold it back and insert it several times as a whole, that is, through the insertion hole 8r.
First, knitting is completed in area 8a by knitting to a position corresponding to the upper end of area 8a, and then both leading and trailing colored threads A and B are inserted into both insertion holes 8r, 8I! Move to the first knitting position in the area 8b between the holes and insert both holes 8r, 8I! When the jacquard knitting is repeated between the areas 8a and 8a, the right insertion hole 8I! It is moved to the first knitting position in the right side area 8c, and the same knitting as described above is performed again. Through holes 8r and 8I for three regions 8a, 8b and 8c, respectively! (The number of words is equivalent to the length of)
When the knitting is completed, the three areas are shown in FIG. 5 (a).

(B), (C), The same process as shown in FIGS. 6(A) to 6(E) is performed in reverse to obtain a cover material as shown in FIG. 5(F).

That is, after completing the knitting of the string hole forming parts 3c and 3d, Jacquard knitting is performed while reducing the number of threads by the same number at both ends, and the arcuate edges 1a and lb are knitted at both ends, and finally, as shown in FIG. A), Figure 6 (A), (B).

Knit in the same manner as shown in (c) and configure the string through hole configuration.
form b.

After the knitting is completed, the arcuate edges 1a and lb, which are both adjacent ends of the four sides, are sewn together to cover the corners on both sides of the front end of the seat part 11 of the seat 10 and on both sides of the upper end of the backrest part 12. A fitting part 2 is formed to cover this as much as possible. As a result, each spinning speed hole component 3a to 3d on the four sides
Since a series of string passing holes 3 are formed, the rubber string 4 is inserted therethrough and both ends thereof are fastened or sewn together.

On the other hand, the rubber string 6 is inserted through the string passing holes 5a and 5b.
Hooks 6a and 6 are attached to the middle part of the rubber cord 6 pulled out from both ends of the rubber cord 60 and the cut between the cord passing holes 5a and 5b, respectively.
b is attached to complete the manufacturing process.

In addition, in the above-mentioned embodiment, the fitted part 2 is increased at the time of knitting,
The explanation has been given on the case where the arcuate edges 1a and lb are formed by reducing stitches and then sewn.However, after the cover material is knitted into a rectangular shape, the four corners are sewn to have appropriate roundness. It may also be formed by cutting.

Fig. 7 shows a seat cover for a high back seat in which a backrest and a headrest are integrally constructed, and is knitted so that only the part that covers the part corresponding to the headrest is slightly narrowed and extended upward. This forms the cover material. Other knitting conditions are the same as in the embodiment shown in FIGS. 1 to 6, and corresponding parts are given the same numbers.

FIG. 8 is a plan view of the headrest cover 9, which is knitted into a bag shape with knit fabric, and the periphery of the opening 9e is woven with rubber thread to form an elastic ring 9C.
Reinforce the edge 9 using heat-shrinkable thread around the entire periphery of the
d is organized and configured.

In addition, the headrest → bar 9 expands the elastic ring part 9c around the opening 9e against its elasticity, and the headrest 1
Cover this from the top of 3. After it is covered, the outer periphery of the support column 13a is tightened by contraction of the elastic ring portion 9c to prevent it from coming off.

Next, an example of the procedure for knitting the headrest cover 9 as described above using a parallel welding machine, for example, is given in Section 9.10.
This will be explained based on the diagram.

FIGS. 9(a) to 9(c) are explanatory diagrams showing the process of knitting the headrest cover, and FIGS. 10(a) to 10(c) are explanatory diagrams similarly showing the knitting mode. First, as shown in FIG. 9(A), at the beginning of knitting, the rubber knitted portion 9a is knitted over a required length so as to cover the entire width of the headrest 13.

That is, as shown in FIG. 10 (a), the so-called rubber knitting is performed in which the yarn a is alternately passed to the latch needles of the front needle bed F and rear needle bed B of the parallel welding machine.

Next, as shown in FIG. 10(b), so-called bag jacquard knitting is performed, in which bag knitting is performed while performing jacquard knitting to form a checkered pattern as shown in FIG. 6(d) described above. The required number of stitches are added on each return trip, and both ends are knitted into a smooth arc. The ratio of the widening stitches may be set according to the roundness of the part to be knitted. After completing the required number of bag jacquard knitting operations, bag jacquard knitting is then carried out over the entire circumference using base yarn and rubber thread as shown in FIG. 9(c) to form an elastic ring portion 9c.

In knitting the elastic ring part 9c by this bag knitting, the 10th
As shown in Figure (C), the first colored thread a is knitted without any holes, but the rubber thread is knitted with one thread on every second latch needle of the front needle bed F, i & needle bed B, for example. Hanging on a needle, so-called 1
It goes without saying that the number of stitches removed from the rubber thread for x2 knitting may be two or more.

When the knitting of the elastic ring part 9c is completed, the entire periphery of the elastic ring part 9c is knitted several courses using a heat-shrinkable synthetic fiber yarn d (for example, Mobilon) to form a reinforced edge. Form 9d. When knitting is completed, the process moves to a molding step, where the reinforcing edge 9d is heat-treated with steam to shrink the heat-shrinkable yarn d. For this heat treatment, a conventionally known method may be adopted, such as immersing the reinforcing edge portion 9d in hot water at a predetermined temperature, or blowing hot air onto the reinforcing edge portion 9d.

This causes the thread d to contract and form a small loop, reinforcing the periphery of the elastic ring 9C, which has elasticity that is slightly smaller than that of rubber thread but stronger than that of rubber thread, and has an elasticity that is stronger than that of rubber thread. This serves to prevent fraying of the knitted part of the part.

FIG. 11 is a schematic diagram of the rear seat cover 15, which is essentially the same except for the fact that the width is nearly twice that of the front seat cover 1 shown in FIG. There is no difference, and corresponding parts are given the same numbers. The same applies to the knitting process, the knitting content, and the manner in which it is applied to the rear seat.

〔effect〕

As described above, in the product of the present invention, the cover body is made of knit fabric, which is highly elastic and has excellent adhesion to the seat surface, and can be knitted as a whole including the string holes in each part. Because of this, there are very few manual sewing processes, resulting in high manufacturing efficiency.It is also highly durable and can be used for a long time.Furthermore, the number of rubber strings used to maintain the adhesion between the sheet and the cover body is high. In addition, in the method of the present invention, the knitting process occupies most of the man-hours, and the present invention has excellent effects such as easy automation and the ability to provide products at low cost. It is something that plays.
